Tragically, there are millions of Firefox users out there using older versions of Firefox. Their reasons are varied and personal. We get it, change is hard. But know this: Upgrading to the latest Firefox is free and easy, plus it gets you a faster, safer and more stable browser. It’s a scenario full of win.

If you’re a Mozillian reading this post, then you already get it. You know that new releases of Firefox bring a bounty of innovations, gifts and delight. You also know that part of our job as Mozillians is to help users find their way to the most recent version of Firefox that’s out there. If you’re a Firefox Affiliate (and really, why wouldn’t you be?) we’ve launched a new kind of button to help you help the masses get up to date.

These upgrade buttons display a different message depending on whether or not you’re using the most recent version of Firefox. If someone visits your website or blog using an older version of Firefox, they’ll get an upgrade message and be directed to the upgrade Firefox download page. The most recent version Firefox or a different browser (gasp!) and a Firefox brand message appears. Visitors who click on this message are directed to the main Firefox download page.

This button is available in 250×300 and 160×600 pixel sizes and is currently only available for the EN-US locale. We’re hoping to roll it out to the other 17 Affiliates locales in the new few weeks.
